This book has been haunting me. It feels like both my past and my future. My past because so many of the interviews go back to World War II era genocide. My future because it also focuses on the violence and genocide that sprung like a virus as the soviet empire was collapsing. This is a very bleak book. I give it five stars because my criteria is whether or not the book stayed with me and changed me, not because I can say I enjoyed it exactly. Don't read it if you are not in a place where you can handle hearing about the worst of humanity.
